The sun sets in the west.

太阳在西边落下。

The sun sets yon the mountains.

太阳在那边的山脉落下。

The light wans as the sun sets.

太阳落山时，光线衰退了。

The light fades as the sun sets.

当太阳落山时，光线逐渐消失。

The sun sets in the western sky.

太阳在西边的天空落下。

The lake glitters as the sun sets.

太阳落山时，湖面闪闪发光。

The sun sets yonder beyond the hills.

太阳在那边的山丘后面落下。

The sun sets westward every evening.

太阳每天晚上向西落下。

The sun sets in the southwest direction.

太阳在西南方向落下。

The shadow gets longer when the sun sets.

太阳落山时，影子变得更长了。
